As clearly-shown in Figs. 1 and 2, a truck,

denotedfby' the reference numeral 10 is 3 rails 1, which are disposed above the track mounted upon the track rails 8 and is pro vided with supplementary track rails 11,

which, when the truck is on said rails 8, register with the "upper end of the -track rails 8, supported upon a transverse I-beam 12, so that the dum p car 2, drawn upwardly on the'track rails 1', is drawn over andupon the'track rails 11, of the truck 10. Mecha nisms areprovidedfor locking the truck 10, in position upon therailsfS, until thedump car. 2, is received thereon, then releasing the same and automatically locking. the

dump car upon the truck softhat the associated truck. and dumpcar may be hauledupwardlyfon the inclined track rails 9, and the contents of the dump. car .2, discharged] fromthe rear. end thereof into the pit structure 6;, between the widely spaced rails 8.

The truck 10,- consists "of channel side sills l3 and built up'end sills, each of which consists of two channels 14, faced toward Fig. 7 is'a detail section taken onfline -77 of Fig. 3.

by angle corneribracket plates 15. V I 16, are secured upon the top surface of the side view of the end of Fig. 8 is a sectional detail taken on line one another as showniin F igs.'5 and 6, and

with the endsills secured to the side sills Plates respective ,end sill channels 14:, as shown 'clearlyin Figs. 3 and 7, and secured on said the-truck in parallel relation, are the track register with the track rails 1."A pair of diagonally disposed 'truss'i' rods 18, are connected between the respective bracket-plates plates-16, and extending}longitudinally "of 16, as shown -clearly"in,jFig 3. Journaled within the end. sillfchtnnel members 14, as clearly shown in Figs. Band '5, are axles-1'9, and on'thejouter' ends thereof are :rollers or wheels 20,Ladaptedto roll upoirtlie track rails 8-9. Extending centrally and long tudinally' of the truck frame, are"inter1nedi ate" channel sills 21, having their ends se cured to the interior surface of the end sills v by bracket plates 22. 1

The entire truck 10, is'held secured in latched position bya latch lever '25, whi'ch,a's shown in Fig. 4, engages overthe upper'en'dof the transverse I-beam 12 'Saidilatch lever- 25, is

pivoted upon therear end "sill 0f the truck and provided with a tail lever extension 26, to which s'conhected a-long actuatmg link-or 'rod27. The' forwardend of" said actuating link or-rod 27, is pivotally con-- the intermediate link 27, to release thetruck for movement. Upwardly extending an d r'e'arwardlybent bars 29, are" secured to the front end sill of"the -truck,'and are positioned to receiveithe'front' axle of the dump oar engaged 'therebeneath, as clearly shown in F ig.5, to hold the dump -car'to the'truck,

and. prevent tilting of the same therefrom Mechanisms are also provided-for posi-j tivel y 'holding the dump car-"upon the truck co-acting with bars"'29,- for 1 the purpose.

' when the associated truck and dump car are I drawn upwardly upon 'the inclinedtrack This mechanism comprises a latch lever or.

hook member 30, shovvi'i in Figs. 4: and 5, adapted toengage-behind the.front axle of the dump car'f The latch lever-j30,is otally mounted upon upright be'aring mem i bers" 31, secu'red'on the" forward end'of the" intermediate longitudinal 'sills 21, and is provided"with a counterweight 32, which acts normally to hold the latch lever 30, upwardly in a positionshown in Figs. 4 and 5. Said latch lever 30, andcounter-weight lever 32, have rigidly associated therewith a downwardly extending crank 33, and, pivotally connected to the end thereof is a long link or lever 34-, consisting of a pair of flat bars spaced apart and leading rearwardly of the truck-and at its rear end having a plate 35, bolted between the flat bars, with a roller transfericar are drawn upwardly upon the 36, journaled therein. v

i A link 37, asshown in Figsxl and 11, is connectedbetween the latch lever 30, and the downwardly directed crank 33. The ,plate 35, is adapted to abut against theupper end of the transverse I-beam 12, when the truck movesrearwardly after a dumping opera- -t1on to thereby cause actuation of the-crank 33, as shown in Fig. 6, to swing .thelatch lever 30, downwardly, and release the front axle of the dump car for movement ofthe dump car off of the transfer truck. To re.-

ceive the car for the next dumping operation, a normally. upright lever 38, is journaledona pintle shaft secured betweenthe intermediate longitudinal sills 21, and has attached thereto bars orplates 39, on each side thereof, and at its extreme lower'e'n'd is provided with a counterweight 40, consisting of a series of built-up plates which act nor mally to hold said lever 38, in upright position. Securedon one endof the bars 39, as

shown in Fig. 14,]are a series of plates affording another counterweight L1, and onthe otherend of said bars 39, are journaled spaced rollers 42, spaced'apart the same distance as the bars 34,.which constitute the connecting lever between the crank arms 33, and the spacing abutment plate 35. Said rollers 42, are adapted tobe swung upwardly by .a rearward movement .of the lever;38,'be-

neaththe bars 34,, to elevate the sameand, permit the roller 36,- to track over the top- -Q surface of the transverse :I-beam 12,

as shown in Fig. 5, permitting the latch lever 30, to swingupwardly into-normal latching position.

The operation is as follows: I

.The dump car 2, ishauled. upwardly on the inclined trackra-ils -1, by the cable 3, and

moved into'horizontal position upon the transfer truck 10, as shown in Fig. 2. Y As the dump car 2, moves onto the transfer truck, the front axle of the dump car strikes the latch 'leverI30, asshownin dotted lines in Fig. 5,-to depress the same, thereby elevating the counterweight 32, and continuing its movements, strikes againstthe lever'28, which, throughthe link 27, serves to elevate the latch lever 25, to release the transfer truck 10;from the stationary transverse I beam 12. The trackrails 11, mounted upon the transfer truck are, of course, in register with the track rails 1, whereby the dump car is permitted to be drawn onto the transfer sibility of the ,material discharged striking truck, and, byi so moving, the front wheels inclined rails 9, the contents ofthe dump car are discharged rearwardly therefrom into the receivingv pit 6, between the widely spaced track rails 8, so that there is no posthe rails, 'with resultant injury thereto. After the contents of the dump car2, have been discharged, thedraft upon the cable'3, is released, allowingthe transfer truck 10, and dump car 2,to move downwardlyon the rails 9, intoposition on the rails 8, the dump car 2, being prevented fromrolling off of the transfer truck by the hook latchlever 30. As the transfer'truck moves into position on the rails 8, the plates35, onthe end vof the connected bars 34, strike against the transverse I-bea n 12,-thereby throwing the crank arm 33, forwardly todepress the'latch lever 30, and release .thefront axle ofthe dump car. Also, thelatch lever25, on the trans? fer truck, slides overtheupperend ofthe transverse I-beam :12, and latches therewith to lock the transfer truck from -movement. As the dump car continues its rearward 10.0 movement alongon the rails 11, f-the transfertruck, ontoits own rails 1, the front axle strikes the upright lever 38, thereby swinging the same rearward'ly, as shown indotted lines in Fig. .6, so that the rollers 42, -are 1' 0.5 projected upwardly beneath the connected I linksor leverbars 3a,.elevating the zsame so that the roller. 36, on the outer endthereof, tracks over the upper surface of the trans verse beam 12, permitting the counterweight 32, to again throw the latch lever 30, up

, wardly into position to latch with the front axle of the dump car in the neat dumping operation, asin the operationpreviously de scribed I am aware that various details of con struction may be varied through a .wide range without departing flOlThtllB principles of this invention, and I therefore do not purpose limiting the patent granted other-12owise than necessitated by the j prior I art.
